Last year when cryptocurrencies were gaining massively in value each month, I badly wanted to create a personal web project which would let me quickly buy and sell crypto outside of brokers like Coinbase; the problem I ran into was not having a reliable API for doing so. I recently discovered coinlayer, an API which provides rates for hundreds of cryptocurrencies using values from dozens of cryptocurrency exchanges.
- coinlayer is free to use!
- coinlayer provides rates for almost 300 cryptocurrencies
- coinlayer provides rates from 25+ exchanges
- coinlayer’s API is well-designed and very easy to use
- coinlayer supports JSONP
After getting your free API key, it’s time to get started with querying the API for cryptocurrency rates.
